The use of any type of solenoid valve is important when there is a need to be able to automatically control the action of the valve and the flow of media through a system. The valve contains a control unit which uses a magnetic field to power the movement of the plunger in the valve to control the flow.
When systems are used to produce or require the use of chemicals, specialized manufacturing of solenoid valves is required. These chemical resistant solenoid valves are designed with specific materials which are highly resistant to oxidation, corrosion or destruction by chemicals.
Valves can have different designs including 2 and 3-way valves as well as miniature valves. There are various configurations within the design as well as options for seating methods.
Environmental Factors
In addition to choosing chemical resistant solenoid valves in relation to the media through the system, it is also essential to consider the working conditions. This includes the media temperature range as well as the viscosity of the media and pressure through the system.
It is critical to consider the upper and lower limits of these factors and not just the average. Valves are rated for specific uses and exceeding these will result in shorter life cycles and an increased risk of valve failure.
Materials
Ideally, the wetted surfaces of chemical resistant solenoid valves should be constructed with PTFE or polytetrafluoroethylene, also commonly known as Teflon. Not only is this highly corrosion resistant, but it also eliminates the risk of material attaching to the valve, ensuring top valve performance even in low pressure and low flow types of applications.
These valves can be standard sizes and configurations, as well as designed for custom system requirements. In high purity and corrosive environments, choosing a top-quality solenoid valve should always be a priority.
